Tiny Invaders

The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much一until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body, your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ. Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
That way you will not get the same illness twice.
You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune system
strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
antibodies attack it.

Germs can enter the body through the eyes.
A:Right
B:Wrong
C:Not mentioned

Energy Cycle
Do you find getting up in the morning so difficult that it's painful?This might be called laziness,but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you're“hot”.That's true .The time of day when you feel most energetic is when your cycle of body temperature is at its peak .For some people the peak comes during the morning. For others it comes in the afternoon or evening.No one has discovered why this is so,but it leads to such familiar monologues as:“Get up,John!You'll be late for work again!”The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can't change your energy cycle,but you can learn to make your life fit to it better. Habit can help,Dr. Kleitman believes. Maybe you're sleepy in the evening but you must stay up late anyway .Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.
Get off to a slow start which saves your energy .Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble of searching for clean clothes by laying them out the night before .Whenever possible,do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

You are advised to rise with a yawn and stretch because it will_______.
A: help to keep your energy for the day's work
B: help you to control your temper early in the day
C: enable you to concentrate on your routine work
D: keep your energy cycle under control all day
